Neutrophil-Lymphocyte Ratio for Predicting Coronary Artery Lesions in Children With Kawasaki Disease

Background: Coronary artery lesions (CAL) are a specific feature of Kawasaki disease (KD), and develop during the second week of illness. This study was conducted to determine whether Neutrophil: Lymphocyte Ratio (NLR), assessed between the fourth and sixth day of fever onset in children with KD, can predict coronary artery lesion (CAL) development. Methods: In this review of hospital records, data of patients with KD admitted at our center between January, 2016 and January, 2020 was retrieved. The patients were divided into two groups based on the presence of CAL, and clinical characteristics of patients were compared between the two groups. Results: Out of the 79 patients enrolled, CAL was found in 40 (50.6%) patients and intravenous immunoglobulin (IVIg) resistance was seen in 13 (16.5%) patients. Multivariate logistic regression revealed NLR as an independent predictor of CAL [OR (95% CI) 2.0 (1.2-3.1); P<0.001], and erythrocyte sedimentation rate (ESR) [OR (95% CI) 1.03 (1.001-1.1) P=0.04], as an independent predictor of IVIg resistance. NLR ?2.08 was 82% sensitive and 80% specific in predicting CAL. ESR ?88 mm/h was 85% sensitive and 64% specific in predicting IVIg resistance. Conclusions: NLR is an independent predictor of CAL in KD. NLR ?2.08 done between the fourth and sixth day of fever onset may identify children with KD at risk of CAL.

Study on fecal calprotectin in predicting disease activity and mucosal healing in patients with small intestinal Crohn′s disease / 中华消化杂志

Objective:To explore the differences of fecal calprotectin (FC), C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) between colon and small intestinal Crohn′s disease, and their predictive values for disease activity and mucosal healing in patients with small intestinal Crohn′s disease.Methods:From January 2017 to January 2023, 64 patients with Crohn′s disease who underwent capsule endoscopy in the First Affiliated Hospital of Zhejiang Chinese Medical University were enrolled, among them 28 patients had only small intestinal lesions (small intestine group) and 36 patients had lesions involving both small intestine and colon or only colon involvement (ileocolon group). The FC, CRP, and ESR levels of the two groups were detected and compared 15 days before capsule endoscopy examination. Wilcoxon rank-sum test was used for statistical analysis. Receiver operating characteristic curve analysis was used to evaluate the predictive value of FC, CRP, and ESR for disease activity and mucosal healing in patients with small intestinal Crohn′s disease.Results:The FC, CRP, and ESR levels of the small intestine group during the active phase of the disease were 1 689.00 μg/g (727.75 μg/g, 1 800.00 μg/g), 5.67 mg/L (1.00 mg/L, 17.01 mg/L), and 4.50 mm/1 h (2.00 mm/1 h, 11.00 mm/1 h), respectively; while FC, CRP, and ESR levels during the mucosal healing phase were 112.00 μg/g (46.50 μg/g, 130.50 μg/g), 1.00 mg/L (1.00 mg/L, 1.62 mg/L), and 2.00 mm/1 h (2.00 mm/1 h, 5.50 mm/1 h), respectively. The FC, CRP, and ESR levels of the ileocolon group during the active phase of the disease were 1 800.00 μg/g (895.50 μg/g, 1 800.00 μg/g), 4.94 mg/L (3.10 mg/L, 14.80 mg/L), and 10.00 mm/1 h (2.00 mm/1 h, 27.75 mm/1 h), respectively, while FC, CRP, and ESR levels during the mucosal healing phase were 66.00 μg/g (32.50 μg/g, 97.50 μg/g), 1.00 mg/L (1.00 mg/L, 1.55 mg/L), and 2.00 mm/1 h (2.00 mm/1 h, 4.50 mm/1 h), respectively. There were no statistically significant differences in FC, CRP, and ESR between the small intestine group and the ileocolon group during the active phase of the disease and mucosal healing phase (all P> 0.05). In the small intestine group, the levels of FC and CRP of patients during the active phase of the disease were 1 173.00 μg/g (312.00 μg/g, 1 800.00 μg/g) and 2.10 mg/1 L (1.00 mg/L, 16.00 mg/L), which were both higher than those of patients during the mucosal healing phase (112.00 μg/g (46.50 μg/g, 130.50 μg/g) and 1.00 mg/L (1.00 mg/L, 1.62 mg/L)), and the differences were statistically significant ( Z=-4.35 and-2.67, P<0.001 and =0.008). In the small intestine group, the level of ESR of patients during the active phase of the disease was 4.00 mm/1 h (2.00 mm/1 h, 16.00 mm/1 h), and there was no significant difference compared with that of patients during the mucosal healing phase (2.00 mm/1 h (2.00 mm/1 h, 5.50 mm/1 h)) ( P>0.05). When the cut-off level of FC was 188.50 μg/g, the sensitivity, specificity, and area under the curve for predicting disease activity in patients with small intestinal Crohn′s disease was 93.3%, 100.0%, and 0.964, respectively. When the cut-off value of CRP was 3.12 mg/L, the sensitivity, specificity, and area under the curve for predicting disease activity in patients with small intestinal Crohn′s disease was 46.7%, 92.3%, and 0.744, respectively. When the cut-off level of ESR was 10.00 mm/1 h, the sensitivity, specificity, and area under the curve for predicting disease activity in patients with small intestinal Crohn′s disease was 33.3%, 100.0%, and 0.654, respectively. There were no statistically significant differences in the area under the curve between the combinations of FC and CRP, FC and ESR, FC, CRP and ESR, and FC alone for predicting disease activity in patients with small intestinal Crohn′s disease (0.964, 0.959, and 0.959 vs. 0.964, all P> 0.05). There was a statistically significant difference in the area under the curve between the combination of CRP and ESR and FC alone in predicting disease activity in patients with small intestinal Crohn′s disease (0.708 vs. 0.964, Z=-2.57, P=0.010). Conclusions:There are no statistically significant differences in FC, CRP, and ESR between colon and small intestinal Crohn′s disease. FC has a high predictive value for disease activity and mucosal healing in patients with small intestinal Crohn′s disease and has certain clinical application value.

Objective:To investigate the values of combined detection of serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), platelet count (PC), platelet count/mean platelet volume (PC/MPV) and platelet plateletcrit (PCT) in the diagnosis of chronic periprosthetic joint infection (PJI).Methods:From January 2013 to December 2019, 441 patients underwent hip or knee joint revision at Department of Articular Surgery, The First Hospital Affiliated to Xinjiang Medical University. The patients were divided into a chronic PJI group and an aseptic prosthetic loosening group. In the chronic PJI group of 147 cases (86 hip ones and 61 knee ones), there were 64 males and 83 females, with a mean age of 66 (54, 72) years. In the aseptic prosthetic loosening group of 294 cases (210 hip ones and 84 knee ones), there were 98 males and 196 females, with a mean age of 63 (49, 72) years. The preoperative levels of CRP, ESR, PC, PC/MPV and PCT were compared between the 2 groups. The best cut-off value, sensitivity and specificity of the above indicators for the diagnosis of chronic PJI were recorded. The diagnostic efficacy of the 5 indicators in combination for chronic PJI was evaluated by comparing the area under the curve (AUC) among the indicators and analyzing the results of combined diagnostic detections.Results:Except for gender and joint revision site, there was no significant difference in the other general data between the 2 groups, showing comparability ( P>0.05). The levels of CRP, ESR, PC, PC/MPV and PCT in the PJI group were significantly higher than those in the aseptic prosthetic loosening group ( P<0.05). For CRP, ESR, PC, PC/MPV and PCT, respectively, the best cut-off values were 9.05 mg/L, 38.5 mm/h, 288×10 9/L, 29.34 and 0.33%, the sensitivities 83%, 71%, 44%, 44% and 33%, the specificities 85%, 86%, 84%, 84% and 90%, and the AUCs 0.868, 0.822, 0.688, 0.696 and 0.659. For CRP+ESR+PC+PC/MPV+PCT and CRP+PC+PC/MPV+PCT, respectively, the AUCs were 0.871 and 0.882, the sensitivities 80% and 84%, and the specificities 86% and 84%, showing significant differences in the diagnosis of chronic PJI compared with ESR, PC, PC/MPV and PCT alone ( P<0.05). Conclusion:In the diagnosis of chronic PJI, serum CRP and ESR combined with PC, PC/MPV and PCT have a reference value, but PC, PC/MPV or PCT alone only has a limited value.

After treatment, erythrocyte sedimentation rate in each group was significantly decreased compared with that before treatment (both P < 0.05). After treatment, erythrocyte sedimentation rate in the observation group was significantly lower than that in the control group [(26.36 ± 11.29) mm/h vs. (39.89 ± 13.74) mm/h, t = -4.28, P < 0.05]. After treatment, C-reactive protein level in each group was significantly decreased compared with that before treatment (both P < 0.05), and C-reactive protein level in the observation group was significantly lower than that in the control group [(7.52 ± 3.23) mg/L vs. (12.83 ± 5.72) mg/L, t = -4.53, P < 0.05]. After treatment, SLEDAI in each group was significantly decreased compared with that before treatment (both P < 0.05), and SLEDAI in the observation group was significantly lower than that in the control group [(5.52 ± 1.25) points vs. (8.25 ± 2.42) points, t = -5.61, P < 0.05]. Conclusion:Mycophenolate mofetil combined with prednisone and hydroxychloroquine for systemic lupus erythematosus can improve patient's immune function and renal function, reduce the body's inflammatory response, and better lower disease activity.

Comparison between DAS28-ESR and DAS28- CRPus for patients with rheumatoid arthritis: application in a population of southern Brazil

Abstract The Disease Activity Score 28 (DAS28) shows discrepancies when using erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) scores to assess rheumatoid arthritis (RA). This study aimed to verify the agreement between the DAS28-CRP and DAS28-ESR scores in patients with RA from the south of Brazil. A unicentric cross-sectional study was performed (n = 56). The diagnosis of the patients followed the American College of Rheumatology/ European League Against Rheumatism criteria, and their DAS28 were calculated. The DAS28- ESR score was higher than the DAS28-CRP (DAS28-ESR mean 4.8±1.6; DAS28-CRP mean 4.3±1.4) for 83.9% of the patients. The DAS28-CRP and DAS28-ESR scores showed a very strong correlation (Pearson's coefficient = 0.922; P<0.0001, 95% CI +0.87 to +0.95, statistical power 100%). Spearman's correlation coefficient (0.49; P=0.0001, 95% CI +0.25 to +0.67, statistical power 47.54%) showed a moderate correlation between the unique components of the DAS28 formulas. There was agreement between the tests in only 36 of the patients (64.29%). Among the discordant categories, DAS28-ESR overestimated the classification in 16 patients (28.5%). The Kappa coefficient between the categories was 0.465 (SE 0.084, 95% CI +0.301 to +0.630), showing a moderate degree of agreement between the instruments. Although the DAS28-ESR and DAS28-CRP were highly correlated, they differed significantly in terms of patient categorization and should not be used interchangeably

The value of laboratory parameters in predicting endoscopic manifestations of ulcerative colitis after treatment / 中华消化杂志

Objective:To explore the significance of laboratory parameters in predicting the endoscopic manifestations of ulcerative colitis (UC) after treatment.Methods:From January 2015 to December 2020, the clinical data of 68 patients with UC hospitalized and treated in Peking University People′s Hospital were retrospectively and continuously collected. According to the degree of bleeding, vascular pattern, erosion and ulcer under endoscopy before and after treatment, they were divided into progressive group (post-treatment ulcerative colitis endoscopic index of severity (UCEIS) score higher than pre-treatment) and non-progressive group (post-treatment UCEIS score equal to or lower than pre-treatment). The baseline platelet count, platelet volume, platelet hematocrit, platelet distribution width, serum albumin, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and related laboratory parameters were compared between the two groups. And analyzed the significance of related laboratory indexes in predicting the endoscopic manifestations of UC after treatment. Independent sample t test and receiver operating characteristic curve (ROC) analysis were used for statistical analysis. Results:According to the degree of bleeding under endoscopy before and after treatment, the patients were divided into progressive group (12 cases) and non-progressive group (56 cases). The baseline platelet count and platelet volume of the progressive group were higher than those of the non-progressive group ((375.58±154.30) ×10 9/L vs. (288.22±103.76) ×10 9/L, (9.29±1.13) fL vs.(8.52±1.29) fL), and the differences were statistically significant ( t=2.40 and 2.08, P=0.019 and 0.049). According to the degree of vascular texture under endoscopy before and after treatment, the baseline platelet volume and serum albumin level of the progressive group (9 cases) were higher than those of the non-progressive group (59 cases) ((9.58±1.18) fL vs. (8.54±1.26) fL, (41.49±5.08) g/L vs. (36.63±6.14) g/L), and the baseline CRP of the progressive group was lower than that of the non-progressive group (2.26 mg/L(0.95 mg/L) vs.8.64 mg/L (26.08 mg/L) ), and the differences were statistically significant ( t=2.32, 2.32, and z=-2.27, P=0.022, 0.047 and 0.045). According to the degree of erosion and ulcer under endoscopy before and after treatment, CRP and ESR of the progressive group (16 cases) were lower than those of the non-progressive group (52 cases) ((2.21 mg/L(5.26 mg/L) vs. 10.63 mg/L(29.97 mg/L), 14.50 mm/1 h (15.25 mm/1 h) vs.17.00 mm/1 h (11.00 mm/1 h)), and the differences were statisticaly significant ( z=-3.64 and -2.42, P=0.001 and 0.020). The cutoff value of baseline platelet count to assess the progression of bleeding under endoscopy after treatment was 336×10 9/L (sensitivity=0.636, specificity=0.852, area under the curve=0.698). The cutoff value of baseline CRP to assess the progression of erosion and ulcer under endoscopy after treatment was 3.44 mg/L (sensitivity=0.750, specificity=0.727, area under the curve=0.727). Conclusions:The baseline platelet volume, serum albumin and ESR are suggestive of endoscopic mucosal changes in patients with UC after treatment. The baseline platelet count and CRP can predict the efficacy in patients with UC.

OBJECTIVE@#To observe the changes of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and nerve function in patients with spinal tuberculosis before and after surgery, explore the timing of surgical intervention, and evaluate its influence on surgical safety.@*METHODS@#A retrospective analysis was conducted on 387 patients with spinal tuberculosis who received surgical treatment from March 2012 to March 2017, including 278 males and 109 females, aged 12 to 86 years old with an average of (49.9±19.1) years. There were 64 cases of cervical tuberculosis, 86 cases of thoracic tuberculosis, 76 cases of thoracolumbar tuberculosis and 161 cases of lumbar tuberculosis. There were 297 patients with single segmental involvementand 90 patients with multiple segmental involvement. Among them, 62 cases presented neurological damage, and preoperative spinal cord neurological function depended on ASIA grade, 5 cases of grade A, 8 cases of grade B, 39 cases of grade C, and 10 cases of grade D. According to the duration of preoperative antituberculosis treatment, the patients were divided into group A (256 cases, receiving conventional quadruple antituberculosis treatment for 2-4 weeks before surgery) and group B (131 cases, receiving conventional quadruple antituberculosis treatment for more than 4 weeks before surgery). The two groups were compared in terms of gender, age, preoperative complicated pulmonary tuberculosis, lesion site, lesion scope, surgical approach, drug resistance and other general clinical characteristics. ESR, CRP, visual analogue scale(VAS), Oswestry Disability Index (ODI), Frankel grade and postoperative complications were observed.@*RESULTS@#All 387 patients were followed up for 12 to 36 (18.3±4.5) months. There were no significant differences in gender, age, preoperative pulmonary tuberculosis, lesion site, lesion range, surgical approach, preoperative drug resistance and other characteristics between two groups. A total of 32 patients in two groups did not heal after surgery, with an incidence rate of 8.27%. The VAS and spinal cord dysfunction index of the two groups were significantly improved after surgery (@*CONCLUSION@#After 2-4 weeks of anti tuberculosis treatment before operation, patients with spinal tuberculosis could be operated upon with ESR and CRP in a descending or stable period. In principle, patients with spinal tuberculosis and paraplegia should be treated as soon as possible after active preoperative management of the complication without emergency surgery.

Negative association between 25-hydroxyvitamin D and inflammatory markers in rheumatologic diseases / Asociación negativa entre 25-hidroxi vitamina D y los marcadores inflamatorios en enfermedades reumatológicas

Objective: The main purpose of this study was to evaluate serum 25-hydroxyvitamin D (25OHD) levels and its association with in"ammatory markers in patients with rheumatologic diseases (RD). Methods: A cross-sectional study in 154 women with RD (rheumatoid arthritis, spondyloarthritis and other connective tissue diseases) and 112 healthy individuals as a control group (CG) was carried out. Results: No differences in serum and urine calcium, serum phosphate, and urinary deoxypyridinoline were found. RD group had lower 25OHD and higher PTH compared to CG. RD group had higher C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) compared to CG. The overall mean level of 25OHD (ng/ml) was 26.3±12.0 in the CG and 19.4±6.8 in the RD group (p<0.0001). Moreover, CG had lower percentage of individuals with 25OHD de!ciency compared to RD (29.9% vs 53.2%). The femoral neck BMD was signi!cantly lower in postmenopausal RD women compared to CG. 25OHD levels signi!cantly correlated with ESR and CRP as in"ammatory markers. Age, BMI, presence of RD, and CRP were signi!cantly and negatively associated with 25OHD levels through linear regression analysis. According to univariate logistic regression analysis for 25OHD deficiency (<20 ng/ml), a significant and negative association with BMI, presence of RD, ESR and CRP were found. Conclusion: Patients with RD had lower 25OHD levels than controls and the presence of a RD increases by 2.66 the risk of vitamin D de!ciency. In addition, 25OHD has a negative correlation with ESR and CRP as in"ammatory markers. (AU)

Objetivo El objetivo principal de este estudio fue evaluar los niveles séricos de 25-hidroxivitamina D (25OHD) y su asociación con marcadores inflamatorios en enfermedades reumatológicas. Materiales y métodos: Se realizó un estudio transversal en 154 mujeres con enfermedades reumatológicas (artritis reumatoide, espondiloartritis y otras enfermedades del tejido conectivo) y 112 individuos sanos como grupo control (GC). Resultados: No se encontraron diferencias en el calcio sérico y urinario, el fosfato sérico y la desoxipiridinolina urinaria entre el GC y los sujetos con enfermedades reumatológicas. El grupo de pacientes con enfermedades reumatológicas tenía 25OHD más bajo y PTH más alto en comparación con el GC. Asimismo, el grupo de individuos con enfermedades reumatológicas tenía proteína C reactiva (PCR) y velocidad de eritrosedimentación (VES) más altas en comparación con el GC. El nivel de 25OHD (ng/ml) fue 26,3±12,0 en el GC y 19,4±6,8 en el grupo con enfermedades reumatológicas (p<0,0001). Además, el GC presentó un porcentaje menor de deficiencia de 25OHD en comparación con el grupo con enfermedades reumatológicas (29,9% vs 53,2%). La DMO del cuello femoral fue significativamente menor en las mujeres posmenopáusicas con enfermedades reumatológicas en comparación con el GC. La 25OHD correlacionó significativamente con la VES y la PCR como marcadores inflamatorios. El análisis de regresión lineal mostró que la edad, el IMC, la presencia de una enfermedad reumatológica y la PCR se asociaron significativa y negativamente con los niveles de 25OHD. Mientras que el análisis de regresión logística univariada mostró que la deficiencia de 25OHD (<20 ng/ml), se asoció significativa y negativamente con el IMC, la presencia de una enfermedad reumatológica, la VES y los niveles de PCR. Conclusiones: Los pacientes con enfermedades reumatológicas tenían niveles de 25OHD más bajos que los controles y la presencia de una enfermedad reumatológica aumenta en 2.66 el riesgo de deficiencia de vitamina D. Además, la 25OHD mostró correlación negativa con la VES y la PCR como marcadores inflamatorios. (AU)

Clinical observation of extremely elevated erythrocyte sedimentation rate / 中华危重病急救医学

Objective:To analyze the clinical features of adult patients with extremely elevated erythrocyte sedimentation rate (ESR, ESR≥100 mm/1 h), so as improve the ability of clinicians to use erythrocyte sedimentation rate to assist in the diagnosis and treatment of diseases.Methods:A retrospective cohort study was conducted to examine the clinical data of patients with ESR ≥ 100 mm/1 h admitted to the First Affiliated Hospital of Kunming Medical University from January 1st 2019 to December 31st 2019. The age, gender, clinical diagnosis, first ESR level after admission, blood routine, liver function, renal function, coagulation function and C-reactive protein (CRP) within 24 hours after admission were collected. Patient cohorts were divided into youth group (18-65 years old), middle-aged group (66-79 years old) and elderly group (≥80 years old) according to the new standards of human age classification of World Health Organization (WHO) 2019. Patient cohorts were also divided into infectious disease group, hematological disease group, autoimmune disease group, renal failure group and others according to their respective clinical diagnosis. The distribution of extremely elevated ESR in each group, and the correlation between ESR and various laboratory indicators were analyzed.Results:① Among 429 patients with ESR≥ 100 mm/1 h, there were 236 males and 193 females. There was no significant difference in ESR levels between males and females [mm/1 h: 108.00 (103.00, 119.75) vs. 117.00 (105.50, 140.00), P = 0.234]. ② The age of 429 patients ranged from 18 to 98 years old, the average age was (53.70±18.70) years old. There were 310 cases in the youth group, 87 cases in the middle-aged group and 32 cases in the elderly group. The ESR level of the young group was significantly lower than that of the middle-aged group and the elderly group [mm/1 h: 108.00 (103.00, 120.00) vs. 119.00 (107.00, 140.00), 120.00 (110.25, 140.00), both P < 0.01]. ③ The main diagnoses associated with extremely elevated ESR were infectious diseases [157 cases (36.6%)], hematological system diseases [127 cases (29.6%)], autoimmune diseases [74 cases (17.2%)]. Pulmonary infection accounted for 58.0% (91/157) of infectious diseases. Hematopoietic stem cell diseases accounted for 45.7% (58/127), lymphocyte and plasma cell diseases accounted for [37.0% (47/127)] and erythrocyte diseases accounted for [11.0% (14/127)] of the hematological system diseases. Diffuse connective tissue diseases accounted for 75.7% (56/74) of autoimmune diseases. ④ Spearman correlation analysis showed that the extremely elevated ESR in all patients was significantly negatively correlated with the levels of red blood cell count (RBC), hemoglobin (HB) and hematocrit (HCT) (ρvalue was -0.395, -0.381 and -0.383, respectively, all P < 0.01), the ESR was significantly positively correlated with the level of fibrinogen (FIB; ρ= 0.345, P < 0.01). A total of 266 patients were tested for both ESR and CRP, and there was no significantly correlation between ESR and CRP level (ρ= -0.019, P = 0.756). Conclusions:The extremely elevated ESR was more common in pulmonary infections diseases, hematopoietic stem cell diseases, lymphocyte and plasma cell diseases, erythrocyte diseases and diffuse connective tissue diseases. The extremely elevated ESR was significantly correlated with the levels of RBC, HB, HCT and FIB.

Role of erythrocyte sedimentation rate and C-reactive protein as a predictor of severity of cellulitis and necrotising fasciitis

Background: Skin infections are major cause of morbidity and mortality worldwide, affecting more than one person/1000 person/year. Sepsis has a worldwide incidence of more than 20 million cases a year, with mortality due to septic shock reaching up to 50% even in industrialized countries. Acute phase reactants like erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) have been used traditionally as markers for inflammation and are readily available in most centres. Aim was to study the correlation between the values of ESR and CRP with severity of cellulitis and necrotising fasciitis (in term of hospital stay and disease outcome).Methods: This was a prospective observational study conducted at Department of Surgery, GMC and Hamidia Hospital, Bhopal from a period of March 2016 to August 2018.Results: Skin and soft tissue infections are most commonly affects male, diabetes mellitus most common co-morbid condition. Mean value of ESR and CRP in patients who could not survived was 64.44 and 145.92 respectively and value more than 54.95 and 93.41 requires longer hospital stay.Conclusions: ESR and CRP are non-specific test but they are good predictors of severity of cellulitis and necrotising fasciitis not only in planning of management of these cases but also predicting outcome of the disease.

El índice kappa mostró una concordancia "buena" entre el método de Westergren y el método de Wintrobe y "moderada" con los métodos de WBI, MM y MMI. Los resultados del presente estudio muestran que el método de Wintrobe es confiable para su uso en el laboratorio clínico comparado con el de Westergreen.

Abstract Four methods were statistically evaluated for their validity to determine the alternative Erythrocyte sedimentation rate to that of Westergren, which was taken as the "gold standard". The methods evaluated were Wintrobe (WB), Wintrobe inclined (WI) at 45° and two capillary micromethods, one vertical (MM) and one inclined at 45° (MMI). A total of 419 samples were processed by the five methods. Concordance (C), sensitivity (S), specificity (E), positive predictive value (PPV) and negative predictive value (NPV) were evaluated. The results for S, E, PPV, NPV and C were: 93.8%, 93.6, 98.8%, 72.8% and 71% for WB; 86.3%, 85.7%, 97.2%, 52.4% and 54% for WI; 94.6%, 66.6%, 94.1%, 71.4% and 54% for MM and 91.9%, 72.4%, 94.8%, 60.8% and 55% for MMI. The kappa index showed "good" agreement between the Westergren method and the Wintrobe method and "moderate" agreement with the WBI, MM and MMI methods. The results of the present study show that the Wintrobe method is reliable for use in the clinical laboratory compared to the Westergren method.

Platelet count as a novel potential predictor of periprosthetic joint infection / 中国组织工程研究

BACKGROUND: Obtaining synovial fluid for diagnostic test of periprosthetic joint infection is invasive and painful to patients. Platelet count is a regular blood test which has been used as a possible predictor of several infectious diseases. Presumably, it could be one of the indicators of periprosthetic joint infection. OBJECTIVE: To identify the accuracies of platelet combined with white blood cell, erythrocyte sedimentation rate or C-reactive protein in the diagnosis of periprosthetic joint infection. METHODS: Patients undergoing revision arthroplasty from March 2013 to December 2018 in the First Affiliated Hospital of Guangzhou University of Chinese Medicine were retrospectively enrolled. A diagnosis of periprosthetic joint infection was confirmed in 77 patients according to the criterions from the Musculoskeletal Infection Society; the remaining 137 patients were confirmed as aseptic cases. White blood cell, erythrocyte sedimentation rate, or C-reactive protein and platelet count were compared between the two groups. The sensitivity, specificity, positive predictive value, and negative predictive value were calculated. RESULTS AND CONCLUSION: The platelet values were significantly increased in periprosthetic joint infection cases. Sensitivity and specificity of the platelet for periprosthetic joint infection were 64.94% and 86.13%, respectively. Platelet demonstrated a higher accuracy when compared to erythrocyte sedimentation rate and C-reactive protein. In such cases, the platelet shows a certain reference value in confirming the diagnosis of periprosthetic joint infection. Platelet was enough used as adjunct diagnostic tool in patients suspected with periprosthetic joint infection.

The significance of T-SPOT.TB and erythrocyte sedimentation rate test in the diagnosis of simple pulmonary nodules in Xinjiang / 中国胸心血管外科临床杂志

@#Objective    To investigate the diagnostic value of tuberculosis T cell spot test (T-SPOT.TB) and erythrocyte sedimentation rate (ESR) test in the diagnosis of simple pulmonary nodules in Xinjiang. Methods    A retrospective analysis of 72 patients with asymptomatic simple pulmonary nodules in the Department of Thoracic Surgery, the First Affiliated Hospital of Xinjiang Medical University from October 2017 to July 2019 was performed. According to the pathological results, the patients were divided into a tuberculoma group [n=23, including 14 males and 9 females, aged 37-84 (56.91±12.73) years] and a lung cancer group [n=49, including 31 males and 18 females, aged 34-83 (61.71±10.15) years]. The predictive value of T-SPOT.TB and ESR results for the diagnosis of simple pulmonary nodules was evaluated. Results    The positive rate of T-SPOT.TB in the tuberculoma group (69.60%) was higher than that in the lung cancer group (42.90%) (χ2=5.324，P=0.021), with a sensitivity of 69.56% and specificity of 57.14%; the positive ESR was 47.80%in the tuberculoma group and 59.20% in the lung cancer group, and no statistical difference was found between the two groups (χ2=0.981, P=0.322), with a sensitivity of 47.82% and specificity of 40.81%; the area under receiver operating characteristic curve (AUC) was 0.618, the 95% confidence interval of AUC was (0.479, 0.758), and the Youden’s index was 0.267 with a sensitivity of 69.60% and specificity of 57.10%. Difference in the T-SPOT.TB and ESR test results was statistically significant (χ2=4.986, P=0.026), but the correlation between the tests was weak with a Pearson contingency coefficient of 0.199. ESR results in patients with different ages were statistically different (χ2=7.343, P=0.025), but the correlation between age and ESR results was weak with a Pearson contingency coefficient of 0.239; T-SPOT.TB results in patients with different ages were not statistically different (χ2=0.865, P=0.649), and the correlation between age and ESR results was weak with a Pearson contingency coefficient of 0.084. Conclusion    The diagnostic value of T-SPOT.TB and ESR tests is small in the diagnosis of simple pulmonary nodules.

An Evaluated Study of Serum C - reactive protein (CRP) and Erythrocyte Sedimentation Rate (ESR) in a Tertiary Care Hospital

The aim of the study is to evaluate instead serum C – reactive protein level and Erythrocyte sedimentation rate as a monitoring tool for all patients to determine severity of infection, attending the OPD in a tertiary care hospital. Methods: This study was conducted in Department of Microbiology & Pathology in Heritage Institute of Medical Sciences, Varanasi. Serum CRP level was measured by CRP analyzer & ESR by Wintrobe’s method. Results: In above study, A total numbers of 240 cases were included, out of which 43.4% were male and 56.7% were females. Among the total number of patients, 76.7% were CRP positive & rest were CRP negative. While, in case of ESR it was elevated in 63.4% cases & rest were normal before starting the treatment. Conclusion: This study conclude that both CRP and ESR aid in analysis and monitoring of the disease but assessment of serum CRP level is much more sensitive in infections.

Evaluation Of Effect Of Melatonin On Hematological Parameters In Patients Of Periodontitis

Introduction:Considering the immunity enhancing property of melatonin, a study on the evaluation of the effect of melatonin on the hematological parameters in patients suffering from Periodontitis.Methods:This study was con-ducted in the Department of Periodontics, Rural Dental College, Loni. Patients of chronic Periodontitis, of age be-tween 18 to 65 years of either gender ready to give informed consent to participate in the study were included. Postop-erative patients, patients having night duties, drivers and those using heavy machinery, pregnant women, lactating mothers, patients with any clinically significant systemic disease and patients on any other drugs were excluded from the study. Patients were divided into two Groups. Group B received scaling and root planning (SRP) and melatonin 3 mg per day were compared to Group A which received SRP only. The Total Leukocyte count, Differential Leukocyte count and Erythrocyte sedimentation rate of each patient was studied at a baseline, 1st(30 days) visit, 2nd(60 days) visit and 3rd(90 days) visit. Results:Both the groups consisted of 80 subjects each. Group A consisted of 71.25% male and 28.75% female patients. There were 56.25% male and 43.75% female patients in Group B. With respect to visit 3, the TLC was statistically lower in Group B. The neutrophil count of Group B was significantly lower during visit 3 as compared to Group A. The lymphocyte count of Group B was significantly lower than that of Group A dur-ing the visit 1, and also significantly higher during visit 3 on comparison with Group A. There was no statistically sig-nificant difference in the groups with respect to eosinophil and basophil count. The Monocyte count of Group B was statistically lower when compared to that of Group A. There was no statistically significant difference between ESR of Group A & Group B.Conclusions: It can be concluded that melatonin has a positive effect on TLC and differential count of patients of periodontitis, conferring a new facet to the management of periodontitis and an attempt to impede the disease progression.

Clinicopathologic study of Kikuchi's disease in children in a tertiary hospital in South India

Background: The aim of this study was to evaluate the clinical and laboratory characteristics, treatment modalities and outcome of children with Kikuchi's disease.Methods: A retrospective cross-sectional study was conducted among all children, histopathologically diagnosed with KFD.' Clinical, laboratory data and treatment outcomes were analysed.Results: During the study period, 53 children histopathologically confirmed as KFD were enrolled in the study. There were 36 males and 17 females. The lymph node involvements were mostly cervical with bilateral predisposition (63.5%), firm (88%), matted (30.8%) and tenderness (38.5%). Fever, headache, vomiting, chills, myalgia and rash were other common presentations other than cervical lymphadenopathy. The associated laboratory findings include anemia (71.2%), leukopenia especially lymphopenia (31.4%), monocytosis (21.6%), thrombocytopenia (16.3%), elevated CRP (53.1%), ESR (83.7%), LDH (100%) and elevated liver enzymes. Most of the children were managed conservatively (49.1%). Corticosteroids were administered for (22.6 %) of patients. Recurrence occurred in 4 children (7.5 %) and 13 children (24.5%) had other associated diseases.Conclusions: KFD should be suspected in well children with febrile cervical lymphadenopathy, especially with leukopenia, monocytosis, and elevated CRP, ESR, LDH, Liver enzymes. KFD in children can have rarely atypical presentations and coexist with other diseases.

Microbiological profile and outcomes of two-stage revision hip arthroplasty

Background: Prosthetic joint infection (PJI) is one of the most challenging cases that confront modern orthopaedics. Two-stage revision, which is the standard of care for PJI, is the preferred mode of treatment for these infections. Aims and Objectives: To study the microbiological profile of prosthetic joint infections (PJI) in the hip and to assess the efficacy of a two stage revision surgery for PJI. We also aimed to study the sensitivity and specificity of ESR and CRP in the diagnosis of PJI. Materials and Methods: The microbiological profile, clinical and radiological outcomes of 22 patients who had a two-stage revision for PJI of the hip between 2013 and 2017 were retrospectively analysed. PJI was defined using the criteria provided by the International Consensus Statement on PJI 2013. Results: Staphylococcus aureus was found to be the most common organism in PJI. Debridement was successful in removing the organism in 74% of PJI. At the time of re-implantation (second stage), six joints grew organisms that were different from that isolated at the index debridement - coagulase-negative staphylococci (3cases) and enterococci (3cases). Other infection parameters for these patients were negative. None of the patients who had two-stage revision surgery had clinical evidence of reinfection or radiological evidence of loosening at a mean of 2-year follow-up. An ESR cut off of >30mm/hr had a sensitivity of 75% and specificity of 88% in predicting PJI. A CRP >10mg/L had a sensitivity of 75% and specificity of 69%. The sensitivity and specificity of using both ESR and CRP cut-offs in the diagnosis of infection were 57% and 94%, respectively. The positive predictive value was 94% and negative predictive value was 56%. Conclusion: The outcomes of the study justify a two-stage revision arthroplasty for PJI of the hip. The use of ESR and CRP as screening tests for the success of debridement has value - but should be interpreted with caution.

Discusión: la PCT mostró ser el más eficaz que ESD y PCR para predecir bacteriemia. se deben realizar investigaciones con biomarcadores con el objeto de disminuir el uso inadecuado de antibióticos en pacientes con fiebre secundaria a enfermedad y acortar los tiempos de tratamiento en pacientes con infecciones adecuadamente resueltas mejorando ampliamente la calidad de vida en niños con cáncer (AU)

Introduction: To predict infection in early stages in children with cancer, markers such as ESR, CRP, and PCT have been evaluated. Objective: To evaluate the diagnostic precision for bacteremia of these markers on admission of children with fever and acute leukemia (AL) or lymphoma (L) admitted between 2013- 2016. Methods: A retrospective analytical study. Review of the clinical records. Sensitivity, specificity, positive predictive value, negative predictive value, and area under the ROC curve were calculated for each marker in MedCalc® V16.8.4. The study was approved by the Ethics Committee. Results: Overall, 31 children with AL and L were admitted, 19 of whom presented with fever and 12 did not. There were 40 episodes of fever classified into 4 groups: bacteremia 14 (35%), microbiologically documented infection 5 (12.5%), clinically documented infection 2 (5%), and fever of unknown etiology 19 (47.5%). PCT levels were higher in the group with bacteremia with a mean value of 1.17ng/mL (p:0.045). The area under the ROC curve between the groups with and without bacteremia was 0.50 for ESR, 0.65 for CRP, and 0.83 for PCT with a sensitivity of 77.78%, specificity of 66.67%, PPV of 50%, and NPV of 92.86%. Discussion: PCT showed a greater efficacy than ESD and CRP to predict bacteremia. Research on biomarkers should be conducted to reduce the inadequate use of antibiotics in patients with fever secondary to disease and to shorten treatment times in patients with adequately resolved infections, thereby improving quality of life in children with cancer (AU)

Analysis of C-reactive protein, fibrinogen and erythrocyte sedimentation rate in patients with obstructive sleep apnea hypopnea syndrome / 中国基层医药

Objective To investigate the changes of C-reactive protein (CRP),fibrinogen (FIB) and erythrocyte sedimentation rate (ESR) in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS),and their relationship with sleep respiratory parameters.Methods From June 2015 to August 2018,70 OSAHS patients [observation group,apnea hypopnea index (AHI) ≥ 5/h] and 20 persons in the snoring control group (control group,AHI ＜ 5/h) who received the monitor of polysomnography in the Pingxiang People's Hospital were enrolled.The levels of CRP,FIB and ESR were measured and compared between the two groups.The correlations were analyzed between the levels of inflammatory markers and sleep breathing parameters.Results The two groups had no statistically significant differences in age,gender and BMI(all P ＞ 0.05).The CRP,FIB and ESR of the observation group were (4.5 ± 3.0) mg/L,(3.3 ± 0.9) g/L,(11.4 ± 5.4) mm/h,respectively,which were significantly higher than those of the control group [(2.0 ± 1.5) mg/L,(2.9 ± 0.5) g/L,(7.6 ± 2.6) mm/h] (t =5.12,2.68,4.36,all P ＜ 0.05).The level of CRP was positively correlated with AHI,oxygen desaturation index (ODI) (r =0.285,P ＜ 0.05 and r =0.282,P ＜ 0.05),and negatively correlated with the lowest SaO2 and the average SaO2 (r =-0.257,P ＜ 0.05 and r =-0.259,P ＜ 0.05).The level of FIB was positively correlated with AHI,ODI (r =0.430,P ＜ 0.01 and r =0.311,P ＜0.01),and negatively correlated with the lowest SaO2 (r =-0.287,P ＜0.01).There were no correlations between ESR and sleep breathing parameters.Conclusion The levels of CRP,FIB and ESR are increased in OSAHS patients,and the levels of CRP and FIB are proportional to the severity of OSAHS,suggesting that OSAHS patients has systemic inflammatory response.
